In ksem_close_fop(), if we get a pshared semaphore that's not already

update the rf / netbsd32 comment.

(mrg)

don't assume _LP64 == supports COMPAT_NETBSD32.

this is not true for alpha, ia64 and arm32 ports, and the first two
were not building because of it, and the latter would be missing
the oabi support (likely not a big deal, but still wrong.)

add a makefile fragment that tells you if it is supported and include
it where needed to define COMPAT_NETBSD32 when building the normal
kernel (ie, modules & rump.)

fixes alpha build, probably fixes ia64 build.

XXX: still leaves some netbsd32 code in rf_netbsdkintf.c, that should
    be moved into some hooks, but first the configuration setup
    needs to be moved into a common function the netbsd32 code can
    call into, vs living in the switch case itself.

PR bin/53919

Suppress shell error messages while expanding $ENV (which also causes
errors while expanding $PS1 $PS2 and $PS4 to be suppressed as well).

This allows any random garbage that happens to be in ENV to not
cause noise when the shell starts (which is effectively all it did).

On a parse error (for any of those vars) we also use "" as the result,
which will be a null prompt, and avoid attempting to open any file for ENV.

This does not in any way change what happens for a correctly parsed command
substitution (either when it is executed when permitted for one of the
prompts, or when it is not (which is always for ENV)) and commands run
from those can still produce error output (but shell errors remain suppressed).

Fix an old bug (very old) that was made worse in 1.128 (the "${1+$@}"
fixes) where a variable containing a CTL char (the only possibility used
to be CTLESC (0x81)) would lose that character if the variable was expanded
when "set -f" (noglob) was in effect.

1.128 made this worse by adding more 0x8z values (a couple more) which would
see the same behaviour, and one of those was noticed by Martijn Dekker.

The reasoning was that when noglob is on, when a var is expanded, there are
no magic chars, so (apparently) no need to escape anything.  Hence nothing
was escaped .. including any CTL chars that happened to be present.  When
we later rmescapes() the CTL chars that we expect might occur are summarily
removed - even if they weren't really CTL chars, but just data masquerading.

We must *always* escape any CTL char clones that are in the var value,
no matter what other conditions apply, and what we expect to happen next.

While here, fix rmescapes() (and its $(()) clone, rmescapes_nl()) to
be more robust, less likely to forget to delete anything (which was
not the issue here, just the reverse) and in a DEBUG shell, have the
shell abort() if it encounters something in rmescapes() it is not
anticipating, so the code can be made to handle it, or if it should
not happen, we can find out why it did.

XXX pullup -8 (but will need to be via patch, code is quite different).
